Samsung S7 Edge, please help!

i just bought an s7 from craiglist, but this cellphone has a lot of random freezes !, i already did a factory reset with no success, i also already tried safe mode and still freeze every 5 or 7 seconds, it freeze/lag for like about 2 or 3 seconds, Then is good... then it lags/freeze again
no SD card in this phone!

i was wondering if is a problem with the cellphone itself or its probably something wrong with the stock ROM? i was thinking about flashing the phone with a custom ROM or another stock ROM so it maybe solve the freeze/lag problem
